WebIONOSPHERE By Marcel H. De Canck, ON5AU The Earth's Atmosphere Taking a look at the neutral composition of the atmosphere around our planet, we can divide it into three main regions: the homosphere to about an altitude of 90 km (55 miles), the ionosphere to an altitude of about 600 km (370 miles) and the exosphere. See Fig 4.1. The ionosphere is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, a region that includes the thermosphere and parts of the mesosphere and exosphere.
